The Mid Statement and Function

You're probably familiar with the Mid function, which returns a substring of a specified number of characters from its string argument. But are you aware that Mid can also be used to replace characters in the middle of a string? The Mid statement is a bit of an oddity in VB because it alters one of its arguments, but this saves a lot of string concatenation code:

 
Dim Str1 As String
Str1 = "SOME STRING"
If Mid(Str1, 2, 1) = "O" _
        Then Mid(Str1, _
        2, 1) = "A"
MsgBox Str1
